The Su Family Rouge Shop in Yumingwu is the talk of the town. Su Hengzhen, the eldest daughter of the Su family, defies the conventional prejudice that sons should inherit the family trade, not daughters. She cuts her hand to reject the Wang family's betrothal letter and makes rouge from flower extracts.
Xu Changyi, a poor country boy, joins the Su family and uses stone as his raw material to create affordable rouge for ordinary people.
Together, they set out to build a rouge business, but the road ahead is fraught with obstacles. An aunt from the embroidery shop comes to cause trouble, but is it a plot by Ningxiang Pavilion, or a scheme hatched by Manager Wang behind the scenes? What happened to the missing manager of the apothecary?
When the royal family takes an interest in their rouge, will it bring good fortune or disaster? After the Empress develops a rash from using it, she orders them arrested. How will they escape?
In an age when men and women are not treated as equals, how can a woman carve out a world of her own?
